The present invention relates to pyrazolecarboxanilides of the formula I

in which the variables are as defined below: n is zero or 2; m is 2 or 3; X¹ is fluorine or chlorine; X² is halogen; Y is CN, NO₂, C₁-C₄-alkyl, C₁-C₄-haloalkyl, methoxy or methylthio; p is zero or 1; R¹ is fluorine, chlorine, bromine, C₁-C₄-alkyl or C₁-C₄-haloalkyl; R² is hydrogen or halogen; R³ is hydrogen, methyl or ethyl;

W is O or S;

with the proviso that, if

a) W═O, R¹=methyl and R³ is hydrogen, R² is not F, or b) W═O, n=0, m=2, p=0, R² and R³ are hydrogen, R¹ is not trifluoromethyl or difluoromethyl.

Here, in the case of multiple substitution, the substituents X₁ and X₂ may independently of one another have different meanings.

Moreover, the invention relates to processes for preparing these compounds, to compositions comprising them and to methods for their use for controlling harmful fungi, in particular Botrytis.

Pyrazolecarboxanilides having fungicidal action are known from the literature. Thus, for example, EP-A 545.099 and EP-A 589 301 describe biphenylanilides of this type which are monosubstituted at the biphenyl group.

WO 00/14071 describes specific 1,3-dimethyl-5-fluoropyrazolecarboxanilides and their fungicidal action.

Pyrazolecarboxanilides having a specific triple substitution at the biphenyl group are known from WO 03/070705 and JP-A 2001/302605.

WO 2004/103975 provides inter alia iodopyrazolecarboxanilides which differ from the present compounds I in particular in that they have an iodine substituent instead of R¹.

It was an object of the present invention to provide pyrazolecarboxanilides whose fungicidal action is better than that of the compounds of the prior art. We have found that this object is achieved by the compounds I defined at the outset. Moreover, we have found processes for preparing these compounds, compositions comprising them and methods for their use for controlling harmful fungi.

Compared to the known compounds, the compounds of the formula I are more effective against harmful fungi.

The compounds of the formula I can be present in different crystal modifications whose biological activity may differ. They also form part of the subject matter of the present invention.

In the formula I, halogen is fluorine, chlorine, bromine or iodine, preferably fluorine or chlorine;

C₁-C₄-alkyl is methyl, ethyl, n-propyl, 1-methylethyl, n-butyl, 1-methylpropyl, 2-methylpropyl or 1,1-dimethylethyl, preferably methyl or ethyl;

C₁-C₄-haloalkyl is a partially or fully halogenated C₁-C₄-alkyl radical, where the halogen atom(s) is/are in particular fluorine and/or chlorine, i.e., for example, chloromethyl, bromomethyl, dichloromethyl, trichloromethyl, fluoromethyl, difluoromethyl, trifluoromethyl, chlorofluoromethyl, dichlorofluoromethyl, chlorodifluoromethyl, 1-chloroethyl, 1-bromoethyl, 1-fluoroethyl, 2-fluoroethyl, 2,2-difluoroethyl, 2-chloro-2-fluoroethyl, 2,2,2-trifluoroethyl, 2-chloro-1,1,2-trifluoroethyl, 2-chloro-2,2-difluoroethyl, 2-bromo-2,2-difluoroethyl, 2,2-dichloro-2-fluoroethyl, 2,2,2-trichloroethyl, 1,1,2,2-tetrafluoroethyl, 1,1,2,2-tetrachloroethyl, pentafluoroethyl, 2,2,3,3-tetrafluoro-1-propyl, 1,1,2,3,3,3-hexafluoro-1-propyl, 1,1,1,3,3,3-hexafluoro-2-propyl, heptafluoro-1-propyl, heptafluoro-2-propyl, 2,2,3,3,4,4,4-heptafluoro-1-butyl or nonafluoro-1-butyl, in particular halomethyl, with particular preference CH₂—Cl, CH(Cl)₂, CH₂—F, CH(F)₂, CF₃, CHFCl, CF₂Cl or CF(Cl)₂.

The compounds I are suitable for use as fungicides. They are distinguished by excellent activity against a broad spectrum of phytopathogenic fungi in particular from the classes of the Ascomycetes, Deuteromycetes, Peronasporomycetes (syn. Oomycetes) and Basidiomycetes. Some of them are systemically active and can be used in crop protection as foliar fungicides, as soil fungicides and as fungicides for seed dressing.

They are particularly important in the control of a large number of fungi on various crop plants, such as wheat, rye, barley, oats, rice, corn, grass, bananas, cotton, soybeans, coffee, sugar cane, grapevines, fruit and ornamental plants and vegetables, such as cucumbers, beans, tomatoes, potatoes and cucurbits, and also the seeds of these plants.

They are especially suitable for controlling the following plant diseases:

Use Examples

The fungicidal action of the compounds I according to the invention was demonstrated by the following tests:

The active compounds were prepared as a stock solution comprising 25 mg of active compound which was made up to 10 ml using a mixture of acetone and/or dimethyl sulfoxide and the emulsifier Uniperol® EL (wetting agent having an emulsifying and dispersing action based on ethoxylated alkylphenols) in a volume ratio of solvent/emulsifier of 99:1. The mixture was then made up to 100 ml with water. This stock solution was diluted with the solvent/emulsifier/water mixture described to give the desired concentration of active compounds.

Activity Against Gray Mold on Bell Pepper Leaves Caused by Botrytis cinerea, Protective Application

Bell pepper seedlings of the cultivar “Neusiedler Ideal Elite” were, after 2-3 leaves were well developed, sprayed to runoff point with an aqueous suspension having the concentration of active compounds stated below. The next day, the treated plants were inoculated with a spore suspension of Botrytis cinerea which comprised 1.7×10⁶ spores/ml in a 2% strength aqueous biomalt solution. The test plants were then placed into a dark climatized chamber at 22-24° C. and high atmospheric humidity. After 5 days, the extent of the fungal infection on the leaves could be determined visually in %.

In this test, the plants which had been treated with 250 mg/l of compounds 9.1, 9.3, 9.12, 9.13, 9.14, 9.17, 9.18, 9.19, 9.20, 9.30, 9.32, 9.33, 9.35, 9.36, 9.37, 9.38, 9.39, 9.40, 9.42, 9.43, 9.44 and 9.45 from Table 9 showed an infection of at most 20%, whereas the untreated plants were 90% infected.

Activity Against Leaf Blotch on Wheat Caused by Leptosphaeria nodorum

Pots of wheat plants of the cultivar “Kanzler” were sprayed to runoff point with an aqueous suspension having the concentration of active compounds stated below. The next day, the pots were inoculated with an aqueous spore suspension of Leptosphaeria nodorum (syn. Stagonosporoa nodorum, Septoroia nodorum). The plants were then placed into a chamber at 20° C. and maximum atmospheric humidity. After 8 days, the leaf blotch on the untreated but infected control plants had developed to such an extent that the infection could be determined visually in %.

In this test, the plants which had been treated with 250 mg/l of compounds 9.1, 9.2, 9.13 and 9.27 from Table 9 showed an infection of at most 20%, whereas the untreated plants were 60% infected.

Curative Activity Against Brown Rust on Wheat Caused by Puccinia recondita

Leaves of potted wheat seedlings of the cultivar “Kanzler” were inoculated with a spore suspension of brown rust (Puccinia recondita). The pots were then placed into a chamber with high atmospheric humidity (90 to 95%) at 20-22° C. for 24 hours. During this time, the spores germinated and the germ tubes penetrated into the leaf tissue. The next day, the infected plants were sprayed to runoff point with an aqueous suspension having the concentration of active compounds stated below. The suspension or emulsion was prepared as described above. After the spray coating had dried on, the test plants were cultivated in a greenhouse at temperatures between 20 and 22° C. and at 65 to 70% relative atmospheric humidity for 7 days. The extent of the rust fungus development on the leaves was then determined.

In this test, the plants which had been treated with 250 mg/l of compounds 9.1, 9.3, 9.4, 9.5, 9.6, 9.7, 9.8, 9.9, 9.10, 9.11, 9.12, 9.13, 9.14, 9.15, 9.17, 9.18, 9.19, 9.20, 9.21, 9.25, 9.26, 9.27, 9.28, 9.29, 9.33, 9.34, 9.35, 9.36, 9.37, 9.38, 9.39, 9.40, 9.42, 9.43, 9.44 and 9.45 from Table 9 showed an infection of at most 20%, whereas the untreated plants were 90% infected.

Comparative Experiment—Activity Against Gray Mold on Bell Pepper Leaves Caused by Botrytis cinerea, Protective Application

Compound No. 47 of Table 1 from EP-A 0 589 301 was compared to compounds 9.17 and 9.20 according to the invention from Table 9.

Bell pepper seedlings of the cultivar “Neusiedler Ideal Elite” were, after 2-3 leaves were well developed, sprayed to runoff point with an aqueous suspension having the concentration of active compounds stated below. The next day, the treated plants were inoculated with a spore suspension of Botrytis cinerea which comprised 1.7×10⁶ spores/ml in a 2% strength aqueous biomalt solution. The test plants were then placed into a dark climatized chamber at 22-24° C. and high atmospheric humidity. After 5 days, the extent of the fungal infection on the leaves could be determined visually in %.
